SPECIFICATION forming part of Letters ma Nob-54,86 8, titted as 31, 1906. Application filed April 27, 1900. Serial No. 14,614. (No model.)

To all whom it mag concern: I Be it known that I, ELUM BALLINGER, a citizenof the United States, residing in Laramie township, in the county of Shelby and State of Ohio, have inventeda new and useful Pump, of which the following is a specification. a

This invention relates to pumps in general and more particularly to the mechanism thereof for operating the piston-rod; and it has for its object to provide a construction in which there will be an even leverage applied from the handle to the piston-rod and a greater rise in the piston per unit of movement of the handle, thus giving a greater quantity of water at each stroke of the pump. In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is an elevation showing the upper portion of the body of a pump and illustrating the reciprocatory rack carried thereby andthrough the medium of which the piston is operated. Fig. 2 is a central longitudinal section of the structure shown in Fig. 1 and showing the end of the pumphandle and the segmental gear thereof in elevation. Fig. 3 is a transverse section of Fig. 2 on line 2 2 thereof.

Referring now to the drawings, the present invention has relation to the piston-operating mechanism, in which 5 is the body of the pump and which body is of the usual construction at its lower portion and carries the pump-barrel. The upper end of the body of the pump is bifurcated to form two parallel legs 6 and 7, and upon the rear faces of the legs are formed ears 8 and 9, which extend longitudinally of the body of the pump, from the upper end thereof to a point below the lower end of the slot of the bifurcation, and through these ears are formed perforations 10, which aline in pairs. Through the lower- -most of the alining perforations is passed a 45- pin 11, which forms the pivot for the handle of the pump, this handle 12 having at its end a segmental gear 13, through the axis of which is formed a perforation which receives directly the pivot-pin. The handle of the pump is not formed integral with the seg mental gear, but instead is bolted thereto, the gear having a block 15 at its center having a bearing face or shoulder 16, froni which there extends at right angles a lug 17', the handle proper being disposed with its end against the shoulder and with one side face against the adjacent face of the lug, in which position it is held by the bolts above referred to and which are shown at 18 passed through alining perforations through the handle and lug.

The segmental gear 13 engages a rack 20 in the form of a plate having rectangular open ings therethrough and with which the teeth of the gear engage. This rack has a socket 21 at its lower end which receives the upper end of the pistonrod of the pump, so that as the gear is oscillated by a corresponding move ment of the pump-handle the rack will be raised and lowered to raise and lower the pis ton-rod and therewith the piston.

In order to hold the rack 20 slidable in proper relation to the pump=body, a guideway is provided therefor. This guideway is in the form of a loop 21 on the front face of a plate 22, which is adapted to lie snugly against the face of the pump body, at the opposite side thereof from the pump-handle, and on the opposite side of the plate 22 from the loop there is formed a block 23, of such size as to fit snugly between the legs 6 and 7 of the body, the block 23 having transverse perforations there through which are adapted to aline with the upper perforations in the ears 8 and 9 to re ceive pins 25, which act to hold the block, and therewith the plate and loop, in proper position.

The slot 26, which is formed longitudinally of the plate 22, opens into the slot of bifurcation of the body of the pump, and through the shown for attachment of the handle to the segmental gear there is a longitudinal strain upon the lug of the gear as well as a transverse strain, the transverse strain being only slight, and a much stronger structure is secured than is usual. The guideway is held firmly in its operative position, and yet when it is desired to remove it to permit removal of the rack and piston-rod the securing-pins thereof may be readily withdrawn, and the rack may be removed either with or w'ithou removing the guide-loop therefrom.

It will be understood that in practice any suitable materials may be used for the various parts of the structure and that any desired proportions maybe employed without departing from the .spiritof the invention. 1

What is claimed .is

1. In a pump the combination with the body portion having a bifurcated upper end, of a handle having a segmental gear journaled between the legs of the bifurcated portion, a

plate disposed against the body, said plate having a block disposed between the legs of 1 vthe body and having a slot openinginto the slot of the bifurcation of the body to receive the periphery of the gear, a guide upon the plate and a rack slidably disposed in the guide and engaging the gear,said rack beingadapted for attachment of a piston thereto.

2. In a pu mp,the combination with the body portion having a bifurcated upper end, and j ears at the sides of the slot of bifurcation'and T a which the gear projects, a block upon the plate lying between the legs of the body and having perforations for alinement with the perforations of the ears, pins passed through said alining-perforations, alloopiupo'n the outer face of the plate, and a rack slidahly engaged with the loop and engaged with the teeth of the gear, said rack beingadapted for the attachment of a piston-rod'to-i-ts lower end.

In testimony that I claim the, foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
